Specification of Letters Patent.

Patented Feb. 4,1919?.

Application filed February?, 1918. Serial No. 215,797.

To all whom t may concern:

Be it known that a citizen of the United States, and resident of Milwaukee, and State of Visconsin, have invented certain new and useful Improvements in Bowland I do hereby declare that the following is a full, clear, and exact description thereof.

My invention has for its general object to provide a simple, economical and effective pin-setting mechanism for bowling alleys, it being of that general type as disclosed in my Patent No. 1,239,280, dated September 4, 1917, for improvements in pin-setting mechanism.

The specic object of my present invenence to the accompanying illustrations and subsequently claimed.

In the drawingsi Figure 1 represents a sectional elevation of a fragment of a pin of a bowling alley embodying the features of my invention, the section being indicated by line 1-1 of Fig. 2;

Fig. 2, a plan view of the same with the bowling pin in section, and

Fig. 3, a diagram view showing the general arrangement of a group of pins.

-eferring by characters to the drawings,

1 represents a supporting bed for the pins having a shouldered seat 2 therein, the same in this case being illustrated in the form of a recess which has a circular throat portion 2 that is adapted to receive a proportionately smaller circular base 3 of a pin 4. The seat 2 is also formed with an aperture 2, through Which a vflexible cord 5 passes, that is connected to the base of the pin and, in this instance, is shown trained around a sheave 6. This cord is attached to a suitable pin-setting mechanism 21, such, for example,as is disclosed in Patent No. 1239280 before mentioned. Y

Spaced above the bed 1 is the bowling alley floor 7,Y which floor is formed with an I, HUGO LoEwnNBAoH,

in the county .of Milwaukee pin but is seat 2. This slot may the standard type and the false base section 3 is reduced and merged at this point into an oval bottom section 3, which section constitutes in effect a roller that is interposed between the bed and floor 7.

It will also be observed that the pin at its greatest diameter in cross-section is of a dimension which Will cause it to project into lthe slot 8 when said pin is in a down position resting upon the bed 1. confines the pin to a limited the same time permits it to fall a certain distance at any angle which will correspond to the angle of the blowthat it is struck by the ball, for example, as is indicated by thearrows at the point it may fall at the angle indicated by the arrow y, which is out of alinement with the elongated guide slot8. However, before the pin finally comes .to rest Thus` the slot upon the bed, it will be observed that it will contact with one wall of the slot 8, which wall will act as a deflector to throw the pin into its dead position as indicated in dotted lines l4, Fig. 2. Then the pin has been knocked down, the floor is cleared at the point of its fall, whereby the ball may travel in any direction to contact with other standing pins and it will be observed that the falling pin, if struck at the proper angle, will contact with the pins standing whereby a strike will be eiected. This universal floating movement of the pin incidental to its being struck by the ball is an important feature of my invention and obviates the mechanical limitations of the bowling game wherein the pins are liXedly hinged.

en the pin is downed, it will be observed that it will be confined in practical alinement with the guide slot 8 as previously stated, by the loose fit between the pin and said slot, and it is further confined by the limited scope of movement permitted by the slack in the pin-setting cord 5.

en it is desired to reset the pins obviously the resetting mechanism is operated a?, y, that is, if the pin is struck degree, but at dovvn into the slot v the ball to a limited degree,

'to a more or less yinforcing may by hand from the rear of the fioorand the game is again readytobeplayed.

An important function of the shouldered seat 2 of the pin base is that it confines `the base of the pin when said pin is struck by oscillates a certain amount with the shou1 dered seat as a fulcrum `prior :to its nesting 8. Thus the various angles indicated by vthedotted lines in Fig. 2 may be assumed upon the initial fall `of the pin.

The diagram view, Fig. 3, illustrates one of the ordinary set-ups of a group of pins and it yis manifest that, While I lhave .described only one of the pin mechanisms, in practice a group of them are arranged accord-ing to my invention similar ltothe group mentioned. Hence, if the first pin of `the series is struck `correctly it. is possible to `down the entire group of p1ns3by one con- `tacting with the other in the same manner as the blow Would affect fa l.group of pins simply spotted upon an alley lfloor.

I directfattention `to the fact that theedges of the slot 8 may be reinforced by ymetal to prevent `breakage or Wear which will occur degree by the surface `of the pin contacting With said edges. The rebe dispensed with, however, Where hardwood is employed.

I claim:

l. A bowling alley comprising a pin, a

i l supporting bed therefor having-a shouldered seat adapted to receive the pin base, a floor abovethe bed having an elongated vguide slot therein positioned over the bed seat, .through `which slot the pin is adapted to project, and

l pin-setting mechanism connected to the `base of said pm.

Copies of this patent may bo obtained for `positioned Agated slot therein whereby. the pin` five cents each,

2. A bowling alley comprising a pin, a supportingbed therefor having a shouldered seat adapted 'to receive a pin base, a door above the base having an elonassociated With the bed seat Iand permitting limited free movement of the pin in any direction incidental to the same zbeing -knoclred down, and flexible means for resetting the pin.

3. A bowling alley comprising a pin hav-,

ing a flat base of circular contour, a supporting bedtherefor having a shouldered seat of larger diameter than the .pin base and adapted to receive the same, a floor positioned above the bed provided with an elongated slot associated With the pin base, the slot being of such dimensions as to permit a limited free movement :of the jpin in any direction.vvhen rocked upon its shouldered seat but adapted to ultimately Aguide the pin lto its deadi point of rest upon the bed, and fleXilble meansconnected `to `the .pin base for resetting the same.

l. A bowling alley comprising a pin, a supporting bed therefor, means associated with the pin base to permit the same to rock thereon to a limited degree, a floor positioned above the bed provided With an elongated Y oonsin.
